Abstract

L'unité extérieure pour conditionneur d'air de l'invention est équipée d'une partie contour, d'une plaque de séparation séparant une partie interne de ladite partie contour, d'un compresseur, et d'un premier matériau isolant acoustique entourant une partie périphérie externe dudit compresseur, et présente une chambre de machine formée par une partie de ladite partie contour et par ladite plaque de séparation, ledit compresseur étant stocké dans ladite chambre de machine. L'unité extérieure pour conditionneur d'air de l'invention est également équipée d'un second matériau isolant acoustique sous forme de plaque se prolongeant dans une direction verticale au niveau de la chambre de machine. Ledit second matériau isolant acoustique présente un tissu non-tissé agencé sur une surface côté compresseur. Lorsque dans ladite partie contour, une portion configurant une partie face avant de ladite chambre de machine constitue une première partie face avant, une portion configurant une partie face latérale de ladite chambre de machine constitue une première partie face latérale, et une portion configurant une partie face arrière de ladite chambre de machine constitue une première partie face arrière, ledit second matériau isolant acoustique est disposé dans un espace entouré par ladite plaque de séparation, ledit premier matériau isolant acoustique, ladite première partie face avant, ladite première partie face latérale et ladite première partie face arrière, de manière à ne pas être en contact avec ledit premier matériau isolant acoustique, ladite première partie face avant, ladite première partie face latérale et ladite première partie face arrière.
